Longitud

Inch, foot and mile use fixed factors. Errors usually come from early rounding or from mixing land miles and nautical miles.

Volumen

Volume is robust for liquids. For dry ingredients it does not replace weighing because density and packing vary.

Datos

KB, MB and GB are decimal. KiB, MiB and GiB are binary. This distinction explains many apparent storage gaps.

Energía

Food calories are kilocalories. Utility bills use kilowatt-hours. Both are energy units, but in different contexts.

Potencia

PS and hp are not identical. Vehicle data often uses metric horsepower, while US/UK contexts often use mechanical horsepower.
